We spent a week at this apartment and we enjoyed it.
We had a harsh start as we spent some time trying to get inside the building, also the bathroom wasn't clean (Merlisa said that the cleaner assured her that everything was clean so I can't blame her). However, these were the only downsides, as everything else was great. We had a great time in the swimming pool on top of the building. The building itself has got a 24 products store on the first floor so any time we could go and buy food or water. The location is 10/10: it's just one minute away from a SkyTrain and there are dozens of restaurants/shops/pharmacies nearby.
It's a really good choice if you want to spend time in Bangkok alone or with your spouse!
